Firearm suppressor with gas deflector

Abstract

Methods and systems are provided for firearm sound suppressors including a gas deflector. In one example, a suppressor comprises a housing, a projectile entrance, a projectile exit, one or more baffles, and a deflector chamber. The deflector extending outward from the housing and the deflector curving around a central axis of the suppressor.

The invention claimed is: 
     
       1. A suppressor, comprising:
 a projectile entrance and a projectile exit; 
 a baffle chamber within the suppressor, the baffle chamber comprising one or more baffles; 
 a second chamber within the suppressor positioned between the baffle chamber and the projectile entrance; 
 a deflector extending from the projectile entrance outward into the second chamber, 
 an end wall formed on an end of the deflector distal from the projectile entrance, the end wall extending towards a central axis of the suppressor, and the end wall forming an arc around the central axis, the arc extending from a first end disposed on a first side of the central axis to a second end disposed on an opposing side of the central axis. 
 
     
     
       2. The suppressor of  claim 1 , wherein the deflector extends along the central axis of the suppressor. 
     
     
       3. The suppressor of  claim 1 , wherein a concave cavity is formed in a side of the deflector facing the central axis of the suppressor and the concave cavity deflects gas in a radial direction of the central axis. 
     
     
       4. The suppressor of  claim 3 , wherein the end wall forms a partial circumference around the central axis. 
     
     
       5. The suppressor of  claim 1 , wherein the end wall of the deflector is positioned a distance apart from an entrance to the baffle chamber. 
     
     
       6. The suppressor of  claim 1 , wherein the suppressor is formed as a single, unitary structure. 
     
     
       7. The suppressor of  claim 1 , wherein the suppressor is manufactured using additive manufacturing or three-dimensional printing. 
     
     
       8. The suppressor of  claim 1 , wherein a concave cavity is formed in a side of the deflector facing the central axis of the suppressor and the concave cavity extends around the projectile entrance. 
     
     
       9. A firearms system comprising a suppressor, the suppressor comprising:
 a projectile entrance and a projectile exit; 
 a baffle chamber within the suppressor comprising one or more baffles; 
 a deflector extending from the projectile entrance outward toward the baffle chamber, and the deflector having an end wall extending from a forward end of the deflector, the end wall extending in an arc around a central axis of the suppressor, and the arc extending from a first end on a first side of the central axis to a second end on a second, opposing side of the central axis. 
 
     
     
       10. The firearms system of  claim 9 , wherein the deflector extends in an arcuate length 210 degrees or less around one side of the central axis. 
     
     
       11. The firearms system of  claim 9 , wherein the end wall extends toward the central axis of the suppressor. 
     
     
       12. The firearms system of  claim 11 , wherein at least one further baffle tube provides a flow path separate from the baffle chamber. 
     
     
       13. The firearms system of  claim 9 , wherein the suppressor is formed as a single, monolithic structure. 
     
     
       14. The firearms system of  claim 9 , wherein a length of the deflector is between 40% and 80% of a total length from a projectile entrance side of the deflector to an opening of the baffle tube chamber. 
     
     
       15. A suppressor, comprising:
 a projectile entrance; 
 a chamber within the suppressor comprising one or more baffles; 
 a deflector extending from the projectile entrance toward the chamber, an end wall extending from a forward end of the deflector, the end wall extending in an arc around a central axis of the suppressor from a first end of the arc on a first side of the central axis to a second end of the arc on an opposing side of the central axis. 
 
     
     
       16. The suppressor of  claim 15 , wherein the end wall is formed on an end of the concave cavity distal from the projectile entrance, and
 a first length from the projectile entrance to the end wall is greater than a second length from the end wall to the baffle chamber projectile entrance. 
 
     
     
       17. The suppressor of  claim 15 , wherein the suppressor is formed as a single, monolithic structure using additive manufacturing or three-dimensional printing. 
     
     
       18. The suppressor of  claim 15 , wherein the deflector extends cantilevered outward from a housing of the suppressor into the deflector chamber. 
     
     
       19. The suppressor of  claim 18 , wherein the deflector extends at a non-zero angle relative to the central axis of the deflector. 
     
     
       20. The suppressor of  claim 15 , wherein the deflector comprises a concave cavity with an opening of the concave cavity facing a central axis of the suppressor.
